Keywords Vitamins; Minerals; Bone health; Performance; Sports nutrition Abstract Background The prevalence of dietary supplement intake among preadolescent endurance runners is currently unknown. Objective Our aim was to describe use of dietary supplements, higher-risk supplements, and sport foods among preadolescent endurance athletes and identify associated characteristics of dietary supplement users in this population. Design This was a retrospective, cross-sectional study. Participants/setting Participants were 2,113 preadolescent endurance runners (male: n = 1,255, female: n = 858; mean age [plus or minus] standard deviation = 13.2 [plus or minus] 0.9 years). Main outcome measures Use of dietary supplements, higher-risk dietary supplements, and sport foods on 2 or more days per week during the past year. Statistical analyses performed Mann-Whitney U tests, [chi].sup.2 tests, univariate and multivariate analyses. Results Twenty-six percent (n = 551) of preadolescent runners used dietary supplements on 2 or more days per week during the past year; 1.3% (n = 27) reported taking higher-risk supplements. Compared with male runners, female runners reported higher use of 1 or more supplements (32.5% vs 21.7%; P Conclusions More than one-quarter of preadolescent runners regularly consumed dietary supplements. Behaviors consistent with dietary restriction and history of bone stress injury were associated with higher likelihood for supplement use. Further work to understand supplement use patterns and potential value for nutrition education is advised to optimize health of preadolescent runners. * Address correspondence to: Michelle Barrack, PhD, RD, CSSD, FACSM, Department of Family and Consumer Sciences, California State University, Long Beach, CA 90840.
